Description

  The present invention relates to a cold transport container that cools and transports seafood such as squid.

  In general, seafood is often eaten raw, such as sushi and sashimi, and the freshness is quickly reduced. Therefore, it had to be shipped to the market as fresh as possible.

  Conventionally, as a method of transporting seafood without reducing the freshness, a method of filling ice in a foamed polystyrene box and transporting the seafood in it has been widely performed. However, this method has a problem that water generated by melting ice leaks out of the container. Since other cargo is polluted by water leaking out of this container, seafood cannot be transported using existing transportation means such as air mail that carries various cargoes in a mixed manner. Had to be transported by trucks. Also, the water leaking out of the container contained body fluids of seafood and was often drowned on the road when transported, causing odors in many cases.

  As a solution to such problems, prepare a frozen product that contains water in a superabsorbent resin in advance, and store it together with a cold object such as seafood to cool the seafood. A cold box that is conveyed while being conveyed has been proposed (see, for example, Patent Document 1). If this cool box is used, ice is not used for the cooling means, so water does not leak out of the container, and seafood is also transported by existing transportation means such as air mail that carries various packages in a mixed manner. can do.

  Hereinafter, the present invention will be described in detail based on embodiments.

(Embodiment 1)
FIG. 1 is a cross-sectional view of a cold transport container according to the first embodiment of the present invention.

  As shown in this figure, a cold transport container 100 according to this embodiment includes a container main body 10 that stores ice 200 and a squid 300 as a cold object, and is stored in the container main body 10 together with the ice 200 and the squid 300. It is comprised with the water absorption body 20 which absorbs the water which arises when 200 melt | dissolves.

  The container main body 10 has a substantially rectangular parallelepiped shape, and a main body member 11 having a cold insulating portion 11a that is a space in which the ice 200 and the squid 300 are accommodated, and the main body member 11 engaged with the main body member 11. 11 and a lid member 12 for sealing 11. As shown in FIG. 1, a water absorbing body 20 is disposed on the bottom side in the main body member 11, ice 200 and squid 300 are accommodated on the water absorbing body 20, and the lid member 12 is engaged with the main body member 11. The main body member 11 is sealed.

  The material of the main body member 11 and the lid member 12 is not particularly limited. The main body member 11 and the lid member 12 of the present embodiment are formed of foamed polystyrene widely used in boxes that contain seafood.

  In addition, the water absorbent body 20 of the present embodiment includes a highly water absorbent resin that absorbs liquid in a bag made of nonwoven fabric. An example of such a highly water-absorbent resin is sodium polyacrylate.

  As described above, the ice 200 and the squid 300 are accommodated in the cold transport container 100 according to the present embodiment, whereby the squid 300 is cooled. Then, the water generated by the melting of the ice 200 is absorbed by the water absorber 20 and held in the water absorber 20. Therefore, it is possible to prevent the water generated by melting the ice 200 from leaking out of the cold transport container 100.

  Moreover, as described above, the water absorbent body 20 of the cold insulated transport container 100 according to the present embodiment includes a highly water-absorbent resin contained in a bag made of a nonwoven fabric. Such a highly water-absorbent resin forms a gel when absorbing water and retains the water therein, and the absorbed water does not come out of the water-absorbing body 20 again. Therefore, it can prevent more reliably that the water which arises because the ice 200 melt | dissolves leaks out of the cold storage conveyance container 100. FIG.

  The amount of water that can be absorbed by the water absorber 20 is preferably equal to or greater than the amount of water when all of the ice 200 is melted. Thereby, even if all the ice 200 melt | dissolves, since the water absorption body 20 can absorb all the water produced when the ice 200 melt | dissolves, it is ensured that water leaks out of the cold storage conveyance container 100. Can be prevented.

  If the cold transport container 100 according to the present embodiment described above is used, water does not leak out of the container, so that the squid 300 can be used even with existing transportation means such as air mail that carries various packages together. Can be transported.

  The cold insulated transport container 100 according to the present embodiment has been described above, but the cold insulated transport container 100 according to the present embodiment is not limited to this.

  The water absorbent body 20 of the cold transport container 100 according to the present embodiment is formed by storing a highly water-absorbent resin in a bag made of non-woven fabric. If the water absorbent body can be absorbed, the water absorbent body 20 is formed. The material is not particularly limited. For example, a urethane sponge may be used as the water absorbent body 20. In this case, the sponge is pressed by the weight of the squid 300 and the absorbed water may ooze out of the sponge somewhat, but since the container body 10 is sealed, the water does not come out of the cold transport container 100.

  In the present embodiment, the squid 300 comes into contact with the water absorber 20 when the ice 200 is completely melted. Depending on the material of the water absorbent body 20, the quality of the squid 300 may be affected, so the material of the water absorbent body 20 needs to be selected with care.

  Moreover, in this embodiment, although the water absorbing body 20 was arrange | positioned at the bottom part in the main body member 11, the position where the water absorbing body 20 is arrange | positioned is not limited to this. For example, as shown in FIG. 2, the water absorbing body 20 may be disposed on the side inner wall portion of the main body member 11 of the container main body 10.

  In addition, the ice 200 accommodated in the cold insulated transport container 100 according to the present embodiment may be fresh water ice frozen in fresh water. However, when storing seafood typified by the squid 300, the ice 200 is stored in the container for a long time. Care must be taken because water enters the cells of fish and shellfish housed in relation to osmotic pressure and the quality is likely to deteriorate. Therefore, when such seafood is accommodated, it is more preferable to use seawater ice obtained by freezing seawater in which ice 200 contains an appropriate amount of salt or deep seawater obtained by freezing deep seawater. Since the difference in osmotic pressure between seawater and body fluids of seafood such as squid 300 is small, if seawater ice or deep sea water ice is used for ice 200, moisture will enter the cells of the seafood contained and the quality will be improved. It can be prevented that it falls. In general, when fish and shellfish are cooled at a temperature of 0 ° C. or lower and not frozen, the freshness is most unlikely to decrease. By using seawater ice or deep sea water ice for the ice 200, it is possible to cool the seafood at the last-minute temperature at which the seafood does not freeze, and to further slow down the freshness of the seafood. Further, it is more preferable to use seawater electrolysis ice prepared by freezing seawater by electrolyzing seawater to prepare alkali ion water, adding various minerals to the alkali ion water, and freezing. By using such seawater electrolysis ice for ice 200, the fall of the freshness of the fish and shellfish accommodated can be further delayed by the antioxidant action of alkali ions and minerals contained in seawater electrolysis ice.

FIG. 3 is a cross-sectional view of a cold transfer container 100A according to the second embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the member same as the member of the cold insulated conveyance container 100 of 1st Embodiment, and the overlapping description is abbreviate | omitted.

  The cold insulation transport container 100A according to the present embodiment has a contact prevention member 30 that prevents the squid 300 and the ice 200 disposed in the cold insulation portion 11a of the main body member 11 of the container main body 10 from directly contacting each other. Is arranged. In the present embodiment, a paper that is not easily torn even when wet, such as a cooking sheet, is used as the contact prevention member 30.

  Here, there are a plurality of sharp portions on the surface of the ice 200, and there is a possibility that the cold object is damaged by contacting the cold object with which the sharp portions are accommodated, and the quality is deteriorated. Particularly soft ones such as squid tend to be damaged when they come into contact with the pointed portion of ice.

  In this embodiment, since the contact prevention member 30 is arranged between the squid 300 and the ice 200 arranged in the cold insulation part 11 a of the container body 10, the sharp part of the surface of the ice 200 contacts the squid 300. Thus, it is possible to prevent the squid 300 from being damaged and the quality of the squid 300 from being deteriorated.

  Although the cold insulated transport container 100A according to the present embodiment has been described above, the cold insulated transport container 100A according to the present embodiment is not limited to this.

  The contact prevention member 30 of the present embodiment is made of paper that is not easily torn even when wet. However, if the squid 300 and the ice 200 are prevented from contacting directly, the contact prevention member 30 is The material and its shape are not particularly limited. For example, a polyethylene sheet may be used as the contact prevention member 30.

  In addition, a member formed of a heat insulating material such as polystyrene foam may be used as the contact prevention member 30. By using a member formed of such a heat-insulating material for the contact prevention member 30, not only can the squid 300 be prevented from being damaged at the sharp part of the surface of the ice 200, It is possible to prevent the quality of the squid 300 from deteriorating due to the squid 300 being too cold.

FIG. 4 is an exploded perspective view of a cold transport container according to the third embodiment of the present invention. FIG. 5 is a cross-sectional view of the cold transfer container according to the third embodiment of the present invention. 4 is a partial cross-sectional view. Moreover, the same code | symbol is attached | subjected to the member same as the member of the cold insulated conveyance container of 1st or 2nd embodiment mentioned above, and the overlapping description is abbreviate | omitted.

  As shown in these drawings, in the cold transport container 100B according to the present embodiment, a rectangular plate-like insole member 40 is disposed in the main body member 11 of the container main body 10, and the ice 200 is placed in the space above it. And the squid 300 is arrange | positioned and the water absorbing body 20 is arrange | positioned in the space under it. That is, in the first or second embodiment, the entire space in the main body member 11 of the container main body 10 is the cold insulation part 11a, but in this embodiment, the space in the main body member 11 is partitioned by the insole member 40. The partitioned upper space is a cold insulation part 11a, and the partitioned lower space is a part where the water absorbing body 20 is disposed.

  The insole member 40 is formed with a plurality of drainage portions 40a each having a through hole that penetrates the insole member 40 in the thickness direction. In addition, although the material which forms this insole member 40 is not specifically limited, the insole member 40 of this embodiment is formed with the expanded polystyrene.

  Further, the body member 11 of the container body 10 of the present embodiment has a side wall thick portion 11b in which the bottom side wall inner wall portion is thicker than the side wall inner wall portion on the upper end opening side, and a bottom portion. A bottom projecting portion 11c projecting toward the upper end opening side is formed so as to bisect. The insole member 40 is supported by the side wall thick portion 11b and the bottom protruding portion 11c in a state where the insole member 40 is not in contact with the water absorbent body 20. In addition, the two water absorption bodies 20 are accommodated in total, one by one at the bottom divided by the bottom protrusion 11c of the main body member 11 of the container main body 10.

  As described above, in the cold transport container 100B according to the present embodiment, the space in the main body member 11 of the container main body 10 is partitioned by the insole member 40, and the squid 300 and the water absorbent body 20 that are disposed in the cold insulating portion 11a. There is no contact. Thereby, it is completely eliminated that the water absorbing body 20 affects the quality of the squid 300. Therefore, any material having water absorption can be used as the water absorbent body 20 without any particular limitation. In addition, since the insole member 40 of this embodiment is not in contact with the water absorption body 20, the water absorption body 20 does not receive a pressing force. Therefore, when a urethane sponge is used for the water absorbing body 20, the absorbed water is not leaked out of the sponge again when the sponge is pressed.

  Further, the insole member 40 is formed with a drainage portion 40a. By this drainage part 40a, the water generated by melting the ice 200 arranged in the cold insulation part 11a hangs down under the insole member 40 through the drainage part 40a. The water dripping from the drainage part 40a of the insole member 40 is absorbed by the water absorbent body 20 disposed under the insole member 40 and held in the water absorbent body 20, so that water leaks outside the cold transport container 100B. It can be reliably prevented from coming out.

  The cold insulated transport container 100B according to the present embodiment has been described above, but the cold insulated transport container 100B according to the present embodiment is not limited to this.

  The insole member 40 of the cold transport container 100B according to the present embodiment is a member having a plurality of through holes penetrating in the thickness direction in a rectangular flat plate shape, but prevents contact between the squid 300 and the water absorbent body 20. And if it is a member which has a structure which discharges | emits the water produced when the ice 200 distribute | arranged to the cold insulation part 11a melt | dissolves to the water absorption body 20 side, it will not be limited to this. For example, a saddle-like member may be used as the insole member 40.

  Further, the insole member 40 is a box-shaped member that has a cold insulation portion 11a in which the ice 200 and the squid 300 are accommodated and the outer wall of which prevents the squid 300 and the water absorbent body 20 from contacting each other. It doesn't matter. In this case, it is essential to have the drainage part 40a. Even if the insole member 40 is such a box-shaped member, contact between the squid 300 and the water absorbing body 20 is prevented, and the water generated by the melting of the ice 200 disposed in the cold insulation portion 11a is the water absorbing body. It is absorbed by 20 and held in the water absorbent body 20. Accordingly, it is possible to prevent water generated by melting the ice 200 from leaking out of the cold transport container 100B. Further, the ice 200 is isolated from the outside by a double wall of the outer wall of the insole member 40 and the outer wall of the container body, and the inflow of heat from the outside is further reduced, so that the time for the ice 200 to melt is reduced. It is delayed and the freshness of the squid 300 can be kept longer.
